d4cb819758 cfgfile: support runtime modification
Extend existing cfgfile library with providing new API functions:

rte_cfgfile_create() - create new cfgfile object
rte_cfgfile_add_section() - add new section to existing cfgfile
object
rte_cfgfile_add_entry() - add new entry to existing cfgfile
object in specified section
rte_cfgfile_set_entry() - update existing entry in cfgfile object
rte_cfgfile_save() - save existing cfgfile object to INI file

This modification allows to create a cfgfile on
runtime and opens up the possibility to have applications
dynamically build up a proper DPDK configuration, rather than having
to have a pre-existing one.

216079fb1d cfgfile: support empty value
This commit adds support to the cfgfile library for parsing a key=value
line that has no value string specified (e.g., "key=").  This can be used
to override a configuration attribute that has a default value or default
list of values to set it back to an undefined value to disable
functionality.

f3b1a6981f cfgfile: support configurable comment character
The current cfgfile comment character is hardcoded to ';'.  This commit a
new API to allow the user to specify which comment character to use while
parsing the file.

This is to ease adoption by applications that have an existing
configuration file which may use a different comment character.  For
instance, an application may already have a configuration file that uses
the '#' as the comment character.

The approach of using a new API with an extensible parameters structure was
used rather than simply adding a new argument to the existing API to allow
for additional arguments to be introduced in the future.

1a5efe7499 cfgfile: support global properties section
The current implementation of the cfgfile library requires that all
key=value pairs be within [SECTION] definitions.  The ini file standard
allows for key=value pairs in an unnamed section.

   https://en.wikipedia.org/wiki/INI_file#Global_properties

This commit adds the capability of parsing key=value pairs from such an
unnamed section. The CFG_FLAG_GLOBAL_SECTION flag must be passed to the
rte_cfgfile_load() API to enable this functionality.  Any key=value pairs
found before the first section can be accessed in the section named
"GLOBAL".

f04519d809 lib: add missing include dependencies
Exported header files for use by applications should be self sufficient and
allow out of order inclusion. Moreover, they must include all the system
headers they need for types and macros.

This commit prevents the following errors:

 error: `RTE_MAX_LCORE' undeclared here (not in a function)
 error: `RTE_LPM_VALID_EXT_ENTRY_BITMASK' undeclared
  (first use in this function)

ca743ea84e cfgfile: increase entry name and value sizes
This patch refers to the ABI change proposed for
librte_cfgfile(rte_cfgfile.h). In order to allow
for longer names and values, the values of macro
CFG_NAME_LEN and CFG_VAL_LEN is increased.

eaafbad419 cfgfile: library to interpret config files
This library provides a tool to interpret config files that have
standard structure.

It is used by the Packet Framework examples/ip_pipeline sample application.

It originates from examples/qos_sched sample application and now it makes
this code available as a library for other sample applications to use.
The code duplication with qos_sched sample app to be addressed later.
